Harmful mutations of the BRCA tumor suppressor genes result in a greater lifetime risk for malignancy-breast and ovarian cancers in particular. An increased risk for male breast, fallopian tube, primary peritoneal, pancreatic, prostate, and colon cancers also has been reported. The BRCA gene is inherited in an autosomal dominant pattern and tends to be highly penetrant; thus, there is an increased incidence of these cancers in affected families. Compared with sporadic tumors, BRCA-associated malignancies have unique manifestations, clinical features, and pathologic profiles...

The use of electronic devices with light-emitting screens has increased exponentially in the last decade. As a result, humans are almost continuously exposed to unintentional artificial light. We explored the independent and combined effects of two aspects of screen illumination, light wavelength, and intensity, on sleep, its biological regulation, and related functional outcomes. The 2 × 2 repeated-measure design included two independent variables: screen light intensity (low ([LI] versus high [HI]) and wavelength (short [SWL] versus long [LWL])...

Public health messages can be used to increase awareness about colorectal cancer screenings. Free or inexpensive images for creating health messages are readily available, yet little is known about how a pictured individual's engagement in the behavior of interest affects message outcomes. Participants ( N = 360), aged 50 to 75 years, completed an online survey in which they viewed a colorectal cancer screening message and were then randomly assigned to view one of four different messages about the pictured individual's screening status...

Background: Breast cancer is the most common cancer in women. Monthly breast self-examination (BSE) has been presented as one of the best screening methods available. The aim of this study was to compare effects of both direct and indirect methods of teaching of BSE on knowledge and attitudes of nursing and midwifery personnel. Materials and Methods: The present study was performed on 89 nursing and midwifery personnel in Valiasr hospital of Borujen city. Participants were randomly divided into a direct and an indirect training group...

The properties and photochemical and photophysical behavior of the mycosporine-like amino acids (MAAs) shinorine and porphyra-334 were experimentally evaluated in solutions of direct ionic micelles as simple biomimicking environments. The preferential partition of the natural molecules in the aqueous phase of sodium dodecyl sulfate (SDS) or cetyltrimethylammonium chloride (CTAC) micellar systems is confirmed. Although the proton dissociation of the carboxylic groups in the MAAs is slightly inhibited in CTAC solutions, the molecules are predicted to be in the form of zwitterions in all the explored media around physiological pH...

Drug screening is currently demanding for realistic models that are able to reproduce the structural features of solid tumors. 3D cell culture systems, namely spheroids, emerged as a promising approach to provide reliable results during drug development. So far, Liquid Overlay Technique (LOT) is one of the most used methods for spheroids assembly. It comprises cellular aggregation due to their limited adhesion to certain biomaterials, like agarose. However, researchers are currently improving this technique in order to obtain spheroids on surfaces that mimic cancer extracellular matrix (ECM), since cell-ECM interactions modulate cells behavior and their drug resistance profile...

BACKGROUND: In neuroscience research, mouse models are valuable tools to understand the genetic mechanisms that advance evidence-based discovery. In this context, large-scale studies emphasize the need for automated high-throughput systems providing a reproducible behavioral assessment of mutant mice with only a minimum level of manual intervention. Basic element of such systems is a robust tracking algorithm. However, common tracking algorithms are either limited by too specific model assumptions or have to be trained in an elaborate preprocessing step, which drastically limits their applicability for behavioral analysis...

BACKGROUND AND PURPOSE: Naturally occurring dysfunction in NaV channels results in complex disorders such as chronic pain, making these channels an attractive target for new therapies. In the pursuit of novel NaV modulators, we investigated spider venoms for new inhibitors of NaV channels. EXPERIMENTAL APPROACH: We used high-throughput screens to identify a NaV modulator in venom of the spider Davus fasciatus. Further characterization of this venom peptide was undertaken using fluorescent and electrophysiological assays, molecular modeling and a rodent pain model...

PURPOSE: Chromosome 22q11.2 deletion syndrome (22q11.2DS), the most common cause of DiGeorge syndrome, is quite variable. Neonatal diagnosis traditionally relies on recognition of classic features and cytogenetic testing, but many patients come to attention only following identification of later onset conditions, such as hypernasal speech due to palatal insufficiency and developmental and behavioral differences including speech delay, autism, and learning disabilities that would benefit from early interventions...

Neuropsychological deficits, including difficulties with attention, are well described in children with sickle cell disease (SCD). Very little is known about attention deficit hyperactivity disorder (ADHD) in children with SCD. The objective of this study was to determine the proportion of ADHD in children with SCD referred for neuropsychological evaluation. This prospective, cross-sectional study included patients (age, 4 to 18 y) with SCD and completion of a neuropsychological evaluation between December 2013 and March 2016...

Julian, an 11-year-old boy in the sixth grade with a compliant disposition and a positive attitude, has had a significant decline in his academic performance over the last 2 years. He spends much of his time in the nurse's office with headaches and fatigue. He reports that he cannot concentrate or follow along in class. Vision and hearing screenings were normal.Julian's teachers report that although he has no behavior problem, he is inattentive and does not put forth the effort she feels he is capable of giving...

This study assesses the utility of the primary care behavioral health screener (PCBHS), which the authors have adapted and translated for adult Bosnian refugees (PCBHS-B) living in the Midwest area of the United States, who utilized primary care services within a private physician clinic and a federally qualified health center. The study was conducted from March 2012-April 2013 and included 131 Bosnian respondents, 24% of whom were receiving behavioral health services. Similar to a non-Bosnian U.S. sample, one-third (34...

The self includes complicated and heterogeneous functions. Researchers have divided the self into three distinct functions called "agency," "ownership," and "narrative self". These correspond to psychiatric symptoms, behavioral characteristics and neural responses, but their relationship with brain structure is unclear. This study examined the relationship between the subjectivity of self-related malfunctions and brain structure in terms of gray matter (GM) volume in 96 healthy people. They completed a recently developed self-reported questionnaire called the Embodied Sense of Self Scale (ESSS) that measures self-related malfunctions...

Although understanding their chemical composition is vital for accurately predicting the bioactivity of multicomponent drugs, nutraceuticals, and foods, no analytical approach exists to easily predict the bioactivity of multicomponent systems from complex behaviors of multiple coexisting factors. We herein represent a metabolic profiling (MP) strategy for evaluating bioactivity in systems containing various small molecules. Composition profiles of diverse bioactive herbal samples from 21 green tea extract (GTE) panels were obtained by a high-throughput, non-targeted analytical procedure...
